Patients often seek rehabilitative treatment for severely worn dentition. The etiology of noncarious tooth wear due to attrition, abrasion, and erosion is multifactorial. To treat the worn dentition, it is important to identify and eliminate and/or control the factors that contribute to excessive wear. Many situations requiring complete mouth rehabilitation present with the challenge of a lack of restorative space. To establish a correct occlusal plane and space for prostheses, it is necessary to increase vertical dimension. This may require an increase in occlusal vertical dimension. Also clinicians should be able to choose the appropriate restorative materials to achieve excellence in natural esthetics as well as proper biomechanics and durability. This article presents a method for altering occlusal vertical dimension to restore dentitions with limited restorative space due to loss of tooth structure.

Objectives : The objective of this study is to determine the associations between dietary behaviour and subjective measurements of dental caries and periodontal disease in a cohort of nursing home staff. Methods : A self-reported survey was carried out in 280 nursing home staff in Jeollabukdo Province, Korea. The collected data were analyzed using SPSS Version 19.0 program. Multiple regression analysis was conducted to examine the effects of dietary behavior and food intake on subjective measurements of the two serious dental diseases. Results : The irregular meal tended to increase dietary imbalance and periodontal diseases in the nursing staff. For example, it had influences on the imbalance of sugar, vegetable, and safood intake. Conclusions : It is important to take regular meal because irregular eating behavior tended to increase dietary imbalance and periodontal diseases in the nursing staff.

The purpose of this study was to analyze the effects of dentistry users' perception of concern about oral health on their perception of oral health and behaviors. For this purpose, the researcher sampled the outpatients who had used 2 dentistries in Kangnam, Seoul and another 2 dentistries in Kangbuk, Seoul and a hospital attached to a dental college in Bundang, Kyonggi-do and thereby, conducted a self-administered questionnaire survey from April 4 through 28, 2006. 291 responses from the survey were analyzed using the SPSS 12.0 statistical program. The results of this study can be summarized as follows; 1. 45.0% of the patients perceived that their oral conditions were not healthy, 32% thought normal for their oral conditions and 23% felt healthy for their oral conditions. 2. Less women (44.1%) felt healthy for their oral conditions than men (46.3%). 3. The more negative patients' perception of their oral health was, they were more likely (55.1%) to rely on relatives for choice of a dentistry. 45.0% of this group worried about their oral health always, 15.1% were more or less worried, and 11.9% of them felt that their oral health was good(P < 0.05). 4. 66.0% of the subjects worried about their oral health sometimes, and 27.8% of them worried always, and 6.2% worried little. There was no significant gender difference, but the older they were, they worried more always(P < 0.05). 5. 93.8% of the group who worried about their oral health always had ever had their teeth scaled, and 65.8% of them had regularly had their teeth scaled. Such ratios differed significantly from the group who worried about their oral health sometimes (49.7% and 46.2%, respectively). The three groups differed in terms of regular checks significantly: 56.6%, 45.3% and 33.3%, respectively. And the rate of visiting the dentistry without fail was significantly highest (71.6%) in the first group (P < 0.05).

The majority of chronic gingival ulcerative lesions are known to be due to autoimmune disease such as oral lichen planus, benign mucous membrane pemphigoid or pemphigus vulgaris. Topical or systemic corticosteroids are mainly used and adjuvant drugs like immunosuppressant, anti-inflammatory drugs, antimalarials or antimetabolites can also be prescribed. Because systemic corticosteroids causes various side effects, such as gastrointestinal disturbance, osteoporosis, diabetes or adrenal suppression. So, topical steroid therapy is main treatment for chronic gingival ulcerative lesion confined to small area. However, there's also limitation of topical corticosteroids. The effect of the corticosteroids decreases due to salivary flow and the movement of the tongue, lips, or buccal mucosa. When the lesions are widely distributed or positioned deeply in oral cavity, it is hard to apply the medication on patients' own. Moreover, it can be applied to unaffected mucosa. Although occlusive steroid therapy using stent was reported to minimize taking steroid and overcome the faults of applying topical steroids, it has been used less frequently in the clinical field. Therefore, this report is going to find out the usefulness and the way to utilize clinically through the case which acted satisfactorily by performing topical steroid therapy using stent on chronic ulcerative gingival lesions.

In this study, I have analyzed domestic dental clinics which had introduced CRM for customer satisfaction management. The purpose of this study is to provide information for designing efficient CRM. I would suggest some strategies to carry out CRM as followed. First, promote long-term relationship with customers. Second, select a target patient group and classify customers. Third, set a systematic database up. Fourth, make various channels to communicate with customers. In addition, the following ways are essential to be successful in implementing CRM. First, strengthen the service provided at the Moment of Truth (MOT). Second, organize learning in hospital and all the staff should be customer-oriented. Third, perform systematic "internal marketing".

Objectives: According to variety rapid change of working environment of dental clinics, dental hygienist faced of many job stress in their working place. The aim of this study was to analyze the stress factors. Methods: 206 participants of dental hygienist that working from each a section in Gwang-ju analysed the Job stress questionnaire as used self written. Results: The stress related of job factors was the highest score from 20-25 years old(p<0.05), score from dental clinic under ten persons, score from single women(p<0.05), score from 1 to 3 years old on job career, score from cases without home economic to support. The stress related of the patients was the highest score from 20-25 years old(p<0.05), score from dental clinic under ten persons, score from single women, score from 1 to 3 years old on job career(p<0.05), score from cases live with parents. Conclusions: These results suggest that, on dental hygienists working in the dental clinic and hospital, the stress of job activities have significant effects on dental hygienists. Therefore, it is recommended that the stress is being systematically reduced methods.

Purpose : To determine the efficacy of the N-terminal fragment of B-type natriuretic peptide (NT-proBNP) as a useful diagnostic method in children with incomplete Kawasaki disease (KD). Methods : Ninety-six patients who were diagnosed as having KD between January 2008 and June 2009 were enrolled in the study. American Heart Association recommendations for diagnosis were used, and patients were divided into the complete KD and incomplete KD groups. Blood tests including NT-proBNP were performed on admission day. Nineteen patients who had other febrile diseases other than KD were enrolled as control. Results : Thirty-three patients (34%) had incomplete KD. Change in the lips and oral cavity and conjunctivitis were the most common clinical features, but their frequency was lower than complete KD (76% vs 98%, 76% vs 90%). Patients with incomplete KD exhibited significantly higher NT-proBNP level than that of control ($1,407.7{\pm}1633.5pg/mL$ vs $126.2{\pm}135.5pg/mL$, $P$<0.001). An NT-proBNP cutoff value of 158 pg/mL provided a sensitivity of 81% and a specificity of 74% for diagnosis of incomplete KD. Conclusion : NT-proBNP assay can be clinically useful for the diagnosis of incomplete KD, if the patient has persistent fever, change in the lips and oral cavity, and conjunctivitis, and if the patient with those symptoms is suspected to have incomplete KD.

Calcium hydroxide has been widely used for root canal dressing material in endodontic treatment. This report describes that when the accurate diagnosis and proper nonsurgical endodontic retreatment is applied to periapical lesion with accidentally extruded calcium hydroxide paste, the lesion can be successfully treated. Overfilled calcium hydroxide can affect the healing process, so the overextension of calcium hydroxide agent should be avoided.
